ADHESION LAYER FOR METAL OXIDE UV FILTERS

An adhesion promoting layer is formed between a transparent substrate and a metal oxide layer to prevent the metal oxide layer from delaminating from the substrate. Preferably, the substrate is a transparent polycarbonate, the adhesion promoting layer is a thin, transparent Al or Ag layer, and the m...

Beschreibung
Zusammenfassung:	An adhesion promoting layer is formed between a transparent substrate and a metal oxide layer to prevent the metal oxide layer from delaminating from the substrate. Preferably, the substrate is a transparent polycarbonate, the adhesion promoting layer is a thin, transparent Al or Ag layer, and the metal oxide layer is ZnO, AZO or IZO UV radiation absorption layer. The layers are preferably deposited by arc plasma deposition or by sputtering.
